It appears that there has been lots of discussion on the original topic, thanks for that.
The value to fly with reference to QNH vs QNE was outside the scope of the original question, fair enough, and why I did not make any contribution to the question asked. The only experience I have landing on a runway with my altimeter indicating zero, were those landings I've flown to the ocean, or on sea level runways. I've been comfortable with that, so did not feel I could contribute much to this topic.
If there are any other helpful comments to be made on topic, please do, otherwise, we'll call it a day for this thread.
